(2) background technology
Film metallurgical technology is as a kind of new technique, and its numerous advantages are impelling film metallurgical technology progressively to be applied in the industry-by-industry.In the field of preparation matrix material and intermetallic compound, utilize film metallurgical technology to prepare in the process of matrix material, at first prepare the matrix film, strengthen body at film surface coating one deck, carry out crimp and thermal treatment then, make to strengthen body and the matrix formation matrix material that is closely linked.Matrix material with this technology preparation has the superfine grain structure, makes material possess the high-intensity good plastic deformation ability that possesses simultaneously.
And utilize film metallurgical technology to prepare in the process of intermetallic compound, two kinds of elements forming intermetallic compound are prepared into film respectively, then two kinds of films are alternately stacked, carry out crimp and thermal treatment, form intermetallic compound thereby make two kinds of elements to react effectively.Prepare intermetallic compound with this technology and can promote reaction between the component effectively, and make intermetallic compound have favorable tissue structure and performance.
A.Jakob and M.O.Speidel utilize film metallurgical technology to prepare TiAl intermetallic compound (microstructureand tensile properties of TiAl compounds formed by reactive foil metallurgy, MaterialsScience ﹠amp; Engineering A, 189 (1994), P129-136), to test employed testing apparatus be a heat isostatic apparatus to the film metallurgical that carries out in the text, but this apparatus structure complexity, and relatively more expensive.Therefore, in the field of preparation matrix material and intermetallic compound, film metallurgical technology has brought new opportunity to us, but does not at present also have special and rational in infrastructure, cheap device is used for film metallurgical technology and prepares matrix material and intermetallic compound.
(3) summary of the invention
The object of the present invention is to provide a kind of simple in structurely, easy to operate be used for the device that film metallurgical technology prepares matrix material and intermetallic compound.
The object of the present invention is achieved like this: it comprises compacting tool set; heating unit and temperature control unit; heating unit is placed in the outside of compacting tool set; temperature control unit is the interior temperature-measuring part 9 of footstock that places compacting tool set; compacting tool set comprises mold base 3; mould sleeve 5 and mould footstock 6; mould sleeve 5 places on the base 1 by mold base 3; mould footstock 6 inserts in the mould sleeve 5; the lower end of mould footstock 6 contacts with sample; the upper end contacts with push rod 8; it also comprises atmosphere protection device, and atmosphere protection device is included in mould footstock 6 and is provided with and is used for feeding around the sample passage 7 of shielding gas and the pneumatic outlet 2 on the mould sleeve 5.
The present invention also has some constitutional featuress like this:
1, described heating unit is a heater coil 4;
2, described mould footstock 6 is provided with the passage that is used to place temperature-measuring part 9;
Heating and temperature control unit are used for being controlled at the temperature of sample in the extrusion process compacting tool set among the present invention, and the atmosphere protection parts are used for providing a protective atmosphere to prevent high temperature oxidation etc. in the high temperature pressing process for the sample in the mould.
Heating unit is placed in the outside of compacting tool set; sample in mould and the mould is heated; temperature-measuring part places in the footstock of mould; temperature to sample in mould and the mould is measured and is controlled, shielding gas by the gas passage in the mould footstock enter sample in the mould around sample is protected.On mould footstock 6, be provided with the passage 7 that is used to place the passage of temperature-measuring part 9 and is used for around sample, feeding shielding gas; temperature-measuring part 9 stretches into the temperature of mould footstock 6 interior Measurement dies and sample; after entering in the mould by passage 7, shielding gas around sample, forms a protective atmosphere; then, shielding gas is flowed out by outlet 2.
The present invention utilizes common tabletting machine and custom-designed mould to form the testing apparatus that can be used for film metallurgical technology, the present invention is rational in infrastructure, for film metallurgical technology provides a kind of simple in structure, the easy to operate device that is used to prepare matrix material and intermetallic compound all has great importance for the research of film metallurgical technology and the preparation of matrix material and intermetallic compound.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
(5) embodiment
In conjunction with Fig. 1, below structure of the present invention is described further:
The present invention includes compacting tool set, heating unit and temperature control unit, heating unit is placed in the outside of compacting tool set, temperature control unit is the interior temperature-measuring part 9 of footstock that places compacting tool set, compacting tool set comprises mold base 3, mould sleeve 5 and mould footstock 6, mould sleeve 5 places on the base 1 by mold base 3, mould footstock 6 inserts in the mould sleeve 5, and the lower end of mould footstock 6 contacts with sample, and the upper end contacts with push rod 8.Heating unit comprises heater coil 4; heater coil 4 is enclosed within mould sleeve 5 outsides; on mould footstock 6, be provided with the passage that is used to place temperature-measuring part 9; temperature-measuring part 9 stretches into the temperature of mould footstock 6 interior Measurement dies and sample; it also comprises atmosphere protection device; atmosphere protection device comprises and is used for feeding the passage 7 of shielding gas and the pneumatic outlet 2 on the mould sleeve 5 on every side to sample; form a protective atmosphere after shielding gas enters in the mould by passage 7 around sample, shielding gas is flowed out by outlet 2.
In use; the film for preparing stacked by test requirements document and the mould of packing in; around sample, feed shielding gas then; opening heater block simultaneously makes mould and sample be in required temperature; after reaching temperature sample is suppressed, can be obtained required film metallurgical sample like this.
